我正在安装 phpancake，有一个像这样的文件夹 shema

application/
install/
library/
public/
sql_schema/
install.html
install.php

这条规则是什么意思？

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ /vote/public/index.php [NC,L]

原文

重写有两个部分。第一个指定如果请求的文件名是大小大于 0 的常规文件 (-s)、符号链接 (-l) 或目录 (< code>-d)，重写到任何地方，例如。不采取任何行动。 [NC,L] 表示该规则不区分大小写，并且是这些条件匹配的最后一条规则。

所有其他请求都会转发到 /vote/public/index.php。

此重写的目的是可以不受干扰地从服务器获取实际的现有文件。如果没有第一条规则，每个文件请求（css 和 js 文件、图像等）都会发送到 index.php ，这会让事情变得非常糟糕。

不过，通常这会写在一份声明中。你可以否定条件，然后也可以去掉[OR]语句：

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-s
RewriteCond %{REQUEST_FILENAME} !-l
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ /vote/public/index.php [NC,L]

这与原来的语句是等价的。

The rewrite has two parts. The first one specifies that if the requested filename is a regular file with a size greater than 0 (-s), a symbolic link (-l) or a directory (-d), rewrite to nowhere, eg. take no action. [NC,L] means that the rule is non case sensitive and the last rule that these conditions match.

All other requests are forwarded to /vote/public/index.php.

The purpose of this rewrite is that an actual, existing file can be fetched from the server without interference. Without the first rule, every file request (css and js files, images etc) would go to index.php which would mess things up pretty badly.

Usually this is written in one declaration, though. You can negate the conditions, and then the [OR] statemens can be taken out also:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-s
RewriteCond %{REQUEST_FILENAME} !-l
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ /vote/public/index.php [NC,L]

This is equivalent to the original statement.
